Title: Ice accumulating type heat exchanger
Inventor: KATAOKA HIDEHIKO
IPC: F25B13/00
Filed: 1992-11-30
Abstract: PURPOSE:To realize an efficient cold accumulating operation and a heat radiating operation. CONSTITUTION:A pair of refrigerant pipes 1 and 2, which form an ice accumulating type heat exchanger, are arranged in the form of zigzag in which they run in the vertical direction and are bent at top and bottom positions. In this instance, respective parts running along the axes of the respective refrigerant pipes 1 and 2 are opposed in parallel, and in addition, a refrigerant flowing direction in the pipes 1 and 2 is reversed to each other. By this, a temperaure distribution along the axes in the vicinity of places where these refrigerant pipes 1 and 2 are put side by side becomes substantially uniform, whereby unevenness of temperature in both of the vertical and horizontal directions in the vicinity of these refrigerant pipes 1 and 2 can be eliminated. Further, during a heat radiating operation, ices are not cut by the refrigerant pipes 1 and 2 by the effect of buyoncy, but stay uniformly in the vicinity of the pipes 1 and 2. Thus, heat radiating efficiency and cold accumulating efficiency can both be carried out with high effciency.
